Search for the missing d-wave neutron excitation states in ¹³B

NUCLEAR REACTIONS ²H(¹³B, ¹³B), E=23 MeV/nucleon; measured reaction products, charged particles, deuteron spectrum, angular distribution; deduced inelastic σ(θ). ¹³B; deduced levels, J, π, effective single particle energies. Missing mass method with analysis performed using distorted wave Born approximation (DWBA) and shell model calculations. Analysis of experimentally obtained gap between s and d shells B isotopes - ¹²B, ¹³B, ¹⁴B. Secondary beam of ¹³B produced in ⁹Be(¹⁸O, X), E=0 MeV/nucleon. Inverse kinematics experiment at the EN-course (exotic nuclei) beam line of the Research Center for Nuclear Physics (RCNP), Osaka University.
